* perf: cut review-chat time-to-first-token
The sandbox-less PR review chat paid several blocking network round-trips
before the first token on every message. Cache GitHub App installation
tokens in-process (per scope, until ~10m before expiry, above the proxy's
5m refresh window) so the chat graph factory and proxy stop re-minting one
each turn. Also drop the duplicate thread-metadata read in the commands
proxy and replace the heavy per-message get_review staleness check with a
single lightweight PR head-SHA lookup.

* fix: keep review chat alive when reseed fails
Address review: a moved PR head now triggers _build_pr_context (and thus
get_review). For an existing chat, fall back to the last seeded context on
HTTPException instead of failing the command; fresh chats still surface the
error since they have no prior context.

* fix: scope public reviewer tokens
Co-authored-by: open-swe[bot] <open-swe@users.noreply.github.com>
* refactor: simplify reviewer token wiring; fix push re-scope + red test
- Remove the redundant _check_or_recreate_sandbox_for_proxy /
_refresh_github_proxy_or_recreate_for_proxy wrappers and call the
underlying functions directly (they already default the token to None).
- process_github_push_event: re-scope the GitHub App token when the push
payload lacked repo privacy/id but PR metadata reveals a public repo, so
reviewer.py never proxies a full-installation token for a public PR.
- Clarify the two-token sequence in trigger_pr_review_from_ref.
- Fix pre-existing failing test test_proxy_refresh_failure_recreates_sandbox
and add coverage for _reviewer_token_for_repo + push-event scoping.

* feat: TTL and revocation handling for cached GitHub OAuth tokens [closes AB-2322]
Persist github_token_expires_at alongside github_token_encrypted, treat
expired cache entries as missing so we re-resolve before kicking off
runs, and invalidate the cached ciphertext on a downstream 401 so the
next invocation gets a fresh token instead of replaying a revoked one.

* webapp: forward installation-token expiry to reviewer cache writes
The three reviewer-thread persist sites in webapp.py were calling
get_github_app_installation_token() (no expiry) and persist_encrypted_github_token
without expires_at, so cached App tokens were treated as never-expiring even
though they actually expire in ~1 hour.
